2 Claims.

My invention relates to an improvement in leaf holding deviceswhich is particularly applicable to the visible holding of multiple sheet systems. It may be employed for example to hold ledger sheets or to hold overlapping filing cards or sheets, the particular sheets with which'my device is employed forming no part, of themselves,

of thepresent invention. I I

One purpose is the provision of ready means for holding a plurality of sheets in such fashion that they maybe visibly inspected and, while firmly held in position during inspection and. storage, may very readily be released for the removal or insertion of one or more or all of the sheets involved. I

Another purpose is the provision of improved means for holding such sheets, asa group, in

file, ledger case, backing, or the like. i

Another purpose is 'theprovision offiling means, employing straight posts, which will effect a maximum economy of space and as contrasted, for example, to filing systems in which books with rings or curved posts are employed.

Other purposes will appear from time to time in the course of the specification and claims.

I illustrate my inventionmore or less diagrammatically in in the accompanying drawings where- Figure l is a plan view, with parts in section;

Figure 2 is a section of the line 22 of Figure 1;

Figure 3 is a section onthe line 3-3 of'Figure 1;

Figure 4 is a plan view of the structure of Figure 1 with the partsin a difierent position; Figure 5 is a detail; s Figure 6 is a side elevation; Figure '7 is a section on the line 'l-l of Figure 5. i

v Figure 8 is a plan view of a form of my device;

Figure 9 is a side elevation of the structure of Figure 8; and a I I p Figure 10 is an enlarged section on the line i device may be mounted. It'willbe understood l0-l0 of Figure 8.

Like parts are indicated by like symbols throughout the specification and drawings.

Referring to Figures 8, 9 and 10, I illustrate a form or unit which may be employed with any suitable base or securing structure. 'I show it as including a side or'binder bar 2? with headed. pins 28 secured thereto; Theopposite bar. 29 is shownas havin'g'keyhole apertures -38 to receive these heads and a spring 3! with an'aper- 'ture 32 adapted to engage one of theheads and to hold the "bar ZEinlockedlpbsition. The bar 29 may also be provided with sliding pins 33, each said pin being provided with an enveloping, member 34 partially surrounding and sliding upon the sidebar 29. a 1

34a indicates abutments or upset portions in the strip or bar 29 adapted to' limit the endwise movement of the enveloping members 34, wh e'reby an unintended'escape of themovable pins 33 u from either end of the bar 29 is prevented.

Referring to Figuresl to 7, I'illustrate a unit which [may include a sidebar 9% having a bot tom!" formed integrally therewith and an opposite fiange 92. The bottom- 9 i is provided with an aperture 93 having a tongue 94 at one end thereof. A base portion 95 isprovided which has an upwardlyextending block shaped. member 96 having'an aperture S'Iatone end thereof adapted to receivethe tongue MQL'I'he unit mayfbe locked in position ,bydropping-it with the aperture 93 receivingthe member'fiii as shown in Figure 4. The unit is 'thenslid downwardly into inst,

the position in which it is shown in Figure 2 1 with the tongue 94 penetrating the aperture 91. A spring latch 98 then urges the locking member 99 down into the aperture I00 in the base and locks the unit against unintended movement. .An opposite side bar Illl may be employed having. keyhole apertures I02 receiving the heads I04 of also carry slidably mountedleaf penetrating pins It will be realized that whereas I have described and illustrated practical and operative devices, nevertheless many changes may be made in the size, shape, numberand disposition of parts without departing from the spirit'of my invention. I therefore wish my description and drawings to be taken as in a broad sense illustrative or diagram-. matic rather than as limitingme to the precise showing. f

. '85 the pins I03 on the binder bar flange 90. It may or fingers I05 and the locking spring latch I06.

' The use" and operation of my invention are as 95 indicates any suitable base upon which my that the base may be of wood or metal or any other suitable material, but 1' illustrate. it as by side, the units as such being adaptable for such fixed mounting, 0.1",if desired, to be inserted in any suitable book or hinder not herein shown.

The leaf engaging or clamping unit shown in Figures 1 to '7 includes one side bar 90, which includes a bottomportion 9|, which serves as the means of attachment to the base 95. It will be understood that I may employ also the structure shown in Figures 8, 9 and 10, in which the side bars 21 and 29 are both flat and parallel, and any suitable means may be employed for securing the ends as a whole to any suitable base, binder or the like, which does not of itself form part of the present invention. In either form, however, a group of leaves is confined between side bars tit and IN, or 21 and 29. In each case binding pins 28 or I03 are fixed to one of the side bars, and movable or slideable posts I05 or 33 are slideably mounted upon the opposite side bar. Slideable pins are provided with the enveloping members 34, which slideably support them on the side bars 29 or NH, respectively.

This structure is advantageous in adding leaves or withdrawing leaves from the group of leaves between the two sidebars. In prior art practise it is normal to employ a supplemental bar of some kind, or a temporary securing means, in order to prevent disassociation or misalignment of the leaves, if leaves are being insertedlor, removed in a body of leaves, when part of the body is laid in one direction and part in another. A supplemental bar with binder posts on it has in the past been customarily employed in order to prevent displacement or misalignment of the leaves. This is particularly the case where a binder is em ployed to secure groups of overlapping or staggered record pages where the individual pages are considerably shorter than the strips and are overlaid one upon the other so that the bottom or lower portion of each page is unmasked by the page above. The present structure provides a ready solution of this problem by the employment of slideable pins. The employment of these sliding pins permits a ready relative endwise movement of the two strips in order to release the locking means, without the necessity of drawing the strips outso far as to free the two sets I described units may be arranged on the base side of binder posts. Since the binder posts on one strip slide, the two strips canreadily have imparted tothem a relative endwise movement without separating them by any substantial movement and without unintentionally releasing any of the leaves.

' I claim:

1. In a securing unit for leaves and the like, two strips of sheet metal, a plurality of binding posts fixed upon one of said strips perpendicular to a face thereof, each said binding post having a headportion, the opposite strip having keyhole shaped apertures, the large portions of which are of sufficient size to admit saidheads, the smaller portions of which are of a size insufiicient to permit the escape of said heads therethrough, whereby, when said strips are given a relative endwise movement in generally parallel planes, said binding posts are gripped by the small portions of said keyhole apertures, means for preventing unintended relative endwise movement of said strips, including a spring secured to the exterior of the apertured strip, said spring having an aperture overlying the smaller portion of one of said keyhole apertures and being biased to close approach to the opposed face of said strip, whereby the aperture in said spring is adapted to receive the head of one of said binding posts, and additional binding posts mounted on said opposite strip, the ends of said additionalbinding posts terminating adjacent the opposed face of the first named strip when the strips are assembled, means for mounting the binding posts of said opposite strip for longitudinal sliding movement with respect thereto.

2. In a securing device for leaves and the like.

a unit including a pair of 'bindei' bars, each of longitudinally, and means providing for relative sliding movement between one of said binder bars and the posts thereof.
